Torque Calibration Analysis Equipment compliments
our range of Torque Tools available to customers. The
mechanical analysers can be used for basic torque
adjustment and setting, while the electronic products
offer higher accuracy to enable tool calibration and
torque data analysis.
While primarily used for Hand Tool testing, some of
the analysers also offer the ability to test Power Tools.

Torque Applying Tools are used in a manufacturing
environment to apply a preset torque to a range of
fastening operations in the Automotive, Aerospace,
Electronics and Consumer Products industries.
Adjustable torque applying tools are primarily used
for maintenance and repair operations in industry in
general, where it may be necessary to apply a number
of different torque settings to a range of fasteners.
Some of these torque applying tools are also available
in enhanced versions including 1000 volt Insulated,
Switch (Sw) and Radio Transceiver (RF) options.

QUALITY
All Torqueleader torque equipment
is used to assess and improve the
quality of our customers’ products,
enabling their customers to benefi t
from the assurance that the products
will perform satisfactorily over
long periods
At Torqueleader we take the subject
of quality seriously - both in the
manufacture of Torqueleader tools
and in the comprehensive testing of
all equipment that we supply
STANDARDS
MHH Engineering Co. Ltd. (Manufacturer
of Torqueleader tools) is assessed and
registered to BS EN ISO 9001:2008
Certifi cate FM 363. Hand Tools
and Implements
All Torqueleader tools are
manufactured to the relevant
British and International
Engineering Standards
All Torqueleader tools conform to
the International Standard on Torque
Tools ISO 6789:2003 or as specifi ed UKAS CERTIFICATION
Torqueleader’s testing and calibration
procedures are performed using
equipment traceable through UKAS
(the United Kingdom Accreditation
Service) Accredited Laboratories
For customers who require a full UKAS
Certifi cate with their tools, this can be
provided at an extra cost
Supplier Section - This can be tailored to include our Distributor’s
name and address
Tool Identifi cation Section - This is for easy identifi cation of the tool,
its maximum capacity and its individual serial number
Test Result Section - This gives the normal point at which the tool
was tested, the tolerances and the actual results obtained
Standard Section - This confi rms the standard requirements to which
the tool complies
Note Section - Information regarding slave pointers etc
Traceability Section - The serial numbers of the test equipment and

ACCURACY (Measuring and Calibrated Scale Tools)
Accuracy is the Torque Tools ability to delivery the torque to the joint as set on the tool’s scale, dial or digital display. This is usually expressed as a percentage of the target torque
RESOLUTION (Measuring and Calibrated Scale Tools)
Resolution is the number of divisions that the tool’s full torque range is divided into. This can be displayed as decimal places on a digital display, number of divisions on a dial or graduations on a scale
REPEATABILITY(Preset Tools)
Repeatability is the tool’s ability to consistently apply the same torque in subsequent tightening operations.This is usually expressed as a percentage of the preset torque
ISO 6789:2003The International Standard for Hand Torque Tools states:
The effective working range of a tool is from 20% to 100% of its maximum torque value
The accuracy requirements for Torque Screwdrivers is ±6% of reading and for Torque Wrenches is ±4% of reading or ± 6% for Torque Wrenches below 10 N.m
The maximum torque value for each square drive size
An overload ability of 125% of maximum torque capacity
A calibration interval of 5000 cycles or 12 months
Test and measuring procedures at 23° ±5°C
The maximum permissible uncertainty of measurement of the calibration device shall be ±1% of the indicated value

WHAT IS TORQUE?
Torque is the application of a Force acting at a radial
Distance and tending to cause rotation
Torque is used to create tension
HOW? Referring to the diagram below, it can be seen that as
the nut and bolt are tightened the two plates are clamped
together. The thread converts the applied torque into
tension in the bolt shank. The amount of tension created
in the bolt is critical
An explanation of TorqueInformation on measuring Torque
Support
WHY? The tension in the bolt creates a clamping force
between the two parts. If the clamping force is too low,
the fasteners can work loose due to vibration or movement
between the component parts. If a clamping force is too
high, the fastener may permanently stretch and no longer
apply the required clamping force. In severe cases the
fastener may fail in assembly or during use when under
load. Clamping force is generally referred to as the preload
HOW IS TORQUE CALCULATED?
Torque is the result of multiplying the value of Force
applied by the Distance from the point of application
Comparing the two examples below (A and B) it will be
noted that the same resultant torque can be achieved with
a lower Force if the Distance from the nut/bolt is increased
It should also be realised that some Torque Wrenches are
length dependent which means that the actual torque
applied to the fastener varies if the hand position on the
wrench is varied - even with the wrench preset. This
occurs if the pivot point of the wrench mechanism is not
coincidental with the point of application of torque
Example A
20 Newtons x 1 metre = 20 N.m
(Newton metres)
Example B
10 Newtons x 2 metres = 20 N.m
Let:
T = Torque
F = Force
L = Length of Lever of Wrench
Then:
T = F x L
Force of 20 N
